Oh my... I have a pip and the little bugger started zipping. day 19 only officially started this afternoon. Additionally, the pip and beginning zip are almost middle of the egg, but close to the wrong end... not the air cell end. I can hear the chick peeping though. It's an active one. I'm worried that it hasn't finished absorbing yolk and veins at this point. Of course I'd notice the wee trouble maker after 10 pm on my way to bed. I know it's best to leave it alone, but for how long?
It's not out of the question that my eggs could be ahead of schedule. We had some really warm days, so the house got heated up and I'd say that my incubator temps might have averaged a bit warmer than I'd figured they would when I started out. Usually my ambient room temp is lower... around 65, so I set my incuview accordingly, but the last week or so the house has been well into the 70's. It seemed like the incubator was OK, but when I averaged out the high and low's showing on my accurite backup, it does look like it might have been more like 100-101 rather than 99.5 in there.
